Firebase - iOS Swift: FIRAuth.auth().signOut() not signing out current user

Question

I\'m building an app using Firebase with an initial SignInViewController that loads a sign in page for users to authenticate with email which triggers the follo

I actually had this issue as well. I was also logging out the user (as you are) with the method's provided by Firebase but when I printed to the console it said that I still had a optional user.

I had to change the logic of setting the current user so that it is always configured by the authentication handler provided by Firebase:

var currentUser: User? = Auth.auth().currentUser
var handle: AuthStateDidChangeListenerHandle!

init() {

    handle = Auth.auth().addStateDidChangeListener { (auth, user) in
        self.currentUser = user

        if user == nil {
             UserDefaults.standard.setValue(false, forKey: UserDefaults.loggedIn)
        } else {  
             UserDefaults.standard.setValue(true, forKey: UserDefaults.loggedIn)
        }

    }

}

As long as you are referencing the current user from this handle, it will update the current user no matter the authentication state.
